The Route demo lets you specify an origin and destination as a latitude/longitude coordinates pair or as a place ID. To copy the latitude/longitude coordinates, find and click a location on the map, and then paste the location into the form.
After you select Get route, the demo displays the response from the computeRoutes method as a route on the map.
See the complete example source code
The following demo lets you experiment with creating lots of different kinds of routes. Click the map to copy the latitude/longitude coordinates of a location. Paste the coordinates into the form to get directions.
